Application le July 25,

This invention aims to provide a novel distributor or timer for internal combustion engines, and forothcr purposes, the device being simple in construction, and novel means being provided for operating the switch members.

It is within the province of the disclosure to improve generally and to enhance the utility ot devices of that type to which the invention appertains.

lVith the above and other objects Ain view which will appear as the description proceeds, the invention resides in the combination and arrangement ot' parts and in the details of construction hereinafter described and claimed, yit being understood l that changes in the precise embodiment of the invention herein disclosed, `may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the. drawings A Y Figure 1 shows in elevation, a device constructed in accordance with the invention;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a sectionon the line 3-3 of Figure 2;

Figure 4 is a top plan of the device, the cover having been removed;`

`Figure 5 is across section on the line 5 5 of Figure 2, parts being left in elevation;

Figure 6 is an elevation disclosing one of the switch levers;

Figure 7 is a diagram illustrating one way in which thedevice may be used.

The device forming the subject matter oit this application comprises a casing which is denoted generally by the numeral 1. The casing 1 comprises a metal base 2 having a reduced neck 3. The casing 1 is held against rotation with the shaft, but is rotated by hand, to change the timing, by any suitable means l, here disclosed as a rod which is pivoted at 5 to the base 2 of the casing. Securing elements G hold the tubular body 7 of the casing 1 on the base 2, the body being `formed of insulating material, as is the lid 8 which rests upon and closes the body 7. lVithin thc casing 1 is rotated a rotor 9, the rotor including a cup-shaped body resting on the base 2 of the casing 1, the body 10 preferably being made of metal and being provided with a tubular extension 11 prolonged. through the neck 3 of the casing 1927. Selial'N'O. 208,374.

1. A shaft 12 extends into the member 1l. The exposed end of the member 11 is surrounded by a collar 14;,'a securing element 15 connecting the shaft 12, the extension 11 of the rotor 9, and the collar 14;, the construction being such that the rotor will be secured in the casing 1, for rotation along with the shaft 12. rFhe cup-shaped body 10 of the rotor 9 may contain oil, it desired, for the lubrication of divers moving parts here-y inafter mentioned. Av track l1b, made oirin-` sulating material, is secured within the body 10, the track having a cam 17 which projects toward the axis ot' rotation of the rotor 9, as

Figure 5 will show.

Metal switch terminals 18 are located andare secured, as shown at 23. Binding posts24, accessible from the outside oit the casing 1, are extended through the strips 21 and through thefbody 7. The binding `posts 241 hold flexible conducting membersi 2501i the inner surfaceo'lf thc body 7. The flexible resilient conducting members preterably are made out ot' wire and include arms' 26 formed into helical springs 27, the ends oit' the springs 27 being engaged immediately with the binding posts 241. The arms 26 of the spring 27 merge into a loop-shaped head 2S which is so located that when it is pressed outwardly by a means to be described hereinaitter, it will come into contact with the switch terminal 18.

Brackets 29 are attached by securing elements 30 to the inner surface ot the body 7 and are provided with reduced fins 31 eX- tending between the flanges 32 of switch levers 33, pivot elements connecting the flanges of the switch levers with the iins ol the brackets, the switch-levers, thus, being 'fulcrumed intermediate their ends on the pivot elements 35. Conical springs 36 are secured to the outer ends of the switch levers 33 and are adapted to engage the flexible conducting members 25. The lower or inner ends of the switch levers 33 are pressed outwardly against the inner edge of the annular V21 extend beneath the base 2 of the casing l,

cam track 16 of the rotor 9 by the springs 3G, engaged with the levers 33 and with the lins ot the brackets 29, as shown clearly in Figure 2 of the drawings. It will be understood that there maybe as many or as few of the switch levers 33 and attendant parts as occasion may require. In the present instance, but two levers are shown, in order to avoid confusion in the drawings, there being no novelty in mere duplication, and a mechanic being quite competent to add as many switch levers as may be considered eX- .pedient, provided that he is instructed by the present disclosure. In the lower portion of the tubular body 7, a drain plug 37 may be mounted, as shown clearly in Figure 3.

r`When the shaft .l2 is tui-ned, rotation is imparted to the rotor 9, and the cam 17 tilts the levers 33 one lat a time, the springs being brought into Contact with the heads 28 of the flexible conducting members 25, and the conducting members being pressed into engagement with the switch terminals 18. The circuit through the timer may include the operating means shown at t, the pivot element 5, the base 2 of the casing l, thestri'p 21,'the binding post 24, the flexible or resilient conducting member 25, the switch lterminal 18, and the binding post 20. Figure V7 shows one circuit or method of application for the device forming the subject matter of this application.

The wiring of Figure sure of the spring 34C "on vthe resilient conducting member 25 is released, the conducting member 25 springs away from the switch terminal 18, and the circuit through the machine is opened `at`18-`25, as clearly shown in Figure 2 of the drawings.

That is claimed is l. In Aa device'oi2 the class described, a casing, a rotor mounted to turn in one end `of the casing, a ring carried by the rotor and :ha-ving an internal cam, a switch lever 'liulcrumed intermediate its ends on the side wall of the casing for swinging movement in a direction substantially parallel to the of rotation of the rotor, one end of the lever being disposed within the ring, means .tor holding'said end of the lever yieldably in thepath of the cam, and a circuit-closing means operated by the opposite end of the lever.V

V2.1In a de'viceof the class described, a cup shaped casing, a switch terminal carried by the side wall of the casing and located within the casing, a springeonducting member supported within the casing and yieldablyspaced from the switch terminal, lmeans external Vto the casing for including the terminal and .the conducting member in an electrical support, a rigid lever 'fulcrumed within the casing, a spring carried by the lever and so locatedasxto engage the conducting member and close iton the terminal when the lever is tilted, means for insulating the-lever, a rotor journaled in the casing,

and means carried by the rotor `for tilting the leverto cause the conducting member to close on the terminal through theinstrumentality yof the spring on the lever.

In testimony that I claim the kforegoing as my own, I have hereto aliixed my signature.
